Hello and welcome to HCM
I am a General and family physician and read your mail in detail. At this high level of FBS and PPBS, the cataract surgery
could not be performed. You have to control Blood sugar level before surgery.
You can reduce it by increasing the dose of Insulin
or starting Oral Diabetic drugs with same dose of Insulin you are taking. But consult your Doctor before altering the dose.
Along with the anti diabetic drugs you have to control your diet and change your life style also. You have not written anything about the diet chart and life style you are following. Follow it according to your disease.
